I've got it sort of working. It still does the static link step for  
the subdirectories - but that's quick and the results aren't too  
offensive.

Some oddities: BSD make doesn't see the real subdirs targets in the  
Makefile if there's a NOP one before them. Maybe it's only seeing the  
first - not sure. Accordingly my root Makefile.PL has

package MY;

# Need to strip the default subdirs target otherwise BSD make doesn't
# see the real target for some reason.

sub top_targets {
     my $tt = shift->SUPER::top_targets( @_ );
     $tt =~ s{^ subdirs \s .*? ^(\S) }{$1}msgx;
     return $tt;
}

package main;

The source only Makefile.PLs are bodged up like this:

     sub MY::static {
         return entab( <<'EOM');
     static :: $(FIRST_MAKEFILE) $(OBJECT)
      $(NOECHO) $(NOOP)
     EOM
     }

Which trims the static target down a bit. It's not /too/ ugly :)
